Phys.org / Unraveling the evolution of an extraordinary photosynthesis in a tropical tree species
Plants use sunlight to convert water and carbon dioxide into energy-rich sugars and oxygen in various ways (photosynthesis). Drought is a major challenge in this process. A research team led by Wolfram Weckwerth at the University ...
Phys.org / Plaster-making technique previously attributed to the Romans appears 8,000 years earlier in Motza
Excavations from 2015 to 2021 on the ancient site of Motza, just west of Jerusalem, revealed a sprawling settlement with some surprisingly advanced technology. The site dates back to 7100–6700 BCE during the Pre-Pottery Neolithic ...
Phys.org / Watch as NASA's Curiosity Rover frees its drill from a rock
This series of images shows NASA's Curiosity Mars rover as it got a rock stuck to the drill on the end of its robotic arm, and—after waving the arm and running the drill a few times—finally detached the rock. The imagery ...
Phys.org / Inexpensive material compresses light, paving the way for photonic microcircuits in the terahertz range
A two-dimensional lamellar crystal composed of atomically thin layers of lead iodide (PbI2) could be used to manufacture a new generation of circuits that use light and mechanical vibrations (rather than electrons) to transmit ...
Phys.org / CPR simulator for space use tracks the differences of blood flow in reduced gravity
The new focus on manned missions to the moon and Mars presents countless pressing challenges, including keeping humans alive in hostile environments. What happens when an astronaut or space tourist has a cardiac emergency ...
Phys.org / What if the brain came first? Scientist rethinks the Cambrian Explosion
For decades, scientists have sought to explain the so-called "Cambrian Explosion," a pivotal period over 500 million years ago when a remarkable diversity of animal life appeared in the fossil record. But rather than a sudden ...
Phys.org / Astronomers explore the surface composition of a nearby super-Earth
Using MIRI (Mid-Infrared Instrument) on board the James Webb Space Telescope (JWST), a team of researchers led by former MPIA (Max Planck Institute for Astronomy, Heidelberg, Germany) Ph.D. student Sebastian Zieba (Center ...
Phys.org / A skull full of surprises: Discovering the evolutionary secrets of fish brains
A new study in Proceedings of the Royal Society B reveals the surprising neurological landscape of fish brains. Harvard researchers map the internal structures of ray-finned fishes' brains in 3D detail, discovering brain ...
Phys.org / As sargassum floods Florida beaches, researchers uncover new use as food-grade ingredient
As record-breaking amounts of sargassum seaweed drift toward Florida's shores, researchers at Florida International University are exploring how the coastal nuisance could become a valuable ingredient in everyday foods.
Phys.org / Subglacial CH₄ export from the Greenland Ice Sheet linked to a mid-Holocene warm period
In a new paper, an international team led by scientists from Charles University, Czechia, has brought evidence linking widespread release of methane (CH₄)—a strong greenhouse gas—from the Greenland Ice Sheet (GrIS) to a warmer ...
Phys.org / Planet 9 volunteers double known population of brown dwarfs
A new paper from NASA's Backyard Worlds: Planet 9 project announces that volunteers have essentially doubled the number of known brown dwarfs, with over 3,000 new discoveries made over the past 10 years since the project ...
Phys.org / Polar vortex forecasts gain months of lead time with new climate-based method
Florida State University researchers have discovered how to accurately predict winter weather forecasts months in advance, affording sectors such as agriculture, water management, energy use and public health a longer lead ...
